Compound fault diagnosis of aero-engine rolling element bearing based on CCA blind extraction
2021
IEEE Access
Fault diagnosis of aero-engine spindle bearing is a critical technique of engine prognostics and health management. As is known that the diagnosis of compound fault of aero-engine spindle bearing is very difficult and easily affected by other vibration interference signals. We present a CCA criterion based method for blind extraction of specific fault signal from multi-channel observations, which is applicable to compound fault diagnosis of aero-engine spindle bearing. The proposed method uses
